Question

如何为 RestController ， Service 和 DAO层编写 JUnit 测试用例？

我尝试过MockMvc

@RunWith(SpringRunner.class)
public class EmployeeControllerTest {

    private MockMvc mockMvc;

    private static List<Employee> employeeList;

    @InjectMocks
    EmployeeController employeeController;

    @Mock
    EmployeeRepository employeeRepository;

    @Test
    public void testGetAllEmployees() throws Exception {

        Mockito.when(employeeRepository.findAll()).thenReturn(employeeList);
        assertNotNull(employeeController.getAllEmployees());
        mockMvc.perform(MockMvcRequestBuilders.get("/api/v1/employees"))
                .andExpect(MockMvcResultMatchers.status().isOk());
    }

我如何验证rest控制器和其他层中的 CRUD 方法？

您可以将@RunWith(MockitoJUnitRunner.class)用于模拟 DAO层组件的服务层进行单元测试。您不需要SpringRunner.class。

Complete source code

    @RunWith(MockitoJUnitRunner.class)
    public class GatewayServiceImplTest {

        @Mock
        private GatewayRepository gatewayRepository;

        @InjectMocks
        private GatewayServiceImpl gatewayService;

        @Test
        public void create() {
            val gateway = GatewayFactory.create(10);
            when(gatewayRepository.save(gateway)).thenReturn(gateway);
            gatewayService.create(gateway);
        }
    }

您可以使用@DataJpaTest进行集成测试您的 DAO层

    @RunWith(SpringRunner.class)
    @DataJpaTest
    public class GatewayRepositoryIntegrationTest {

        @Autowired
        private TestEntityManager entityManager;

        @Autowired
        private GatewayRepository gatewayRepository;

        // write test cases here     
    }
